Here are the toots from my Mastodon account. If you’re into ham radio and technology this is a great inclusive server with an awesome mascot called Alex.

It's Alex! A soft brown mastodon holding a handheld radio in their right hand and carrying a blue bag over their shoulder

Talking of maplin. If anyone on this instance and in the UK wants any RP-crimp SMA plugs or sockets then let me know.

I’ll happily send a few (no charge!) to anyone who needs them. I think reverse polarity is generally used for WiFi gear. I have a bunch of each for RG174 and RG58.

I also have a load of other random connectors, just nothing particularly common, so if you’re looking for something odd then let me know and I’ll see what I have.

RP-SMA plugs and sockets. In small polythene bags with cardboard top.

Naturally I ran out of crimp connectors so after digging through my Maplin haul I’ve ended up with a “Clamp-on” BNC plug. And it has loads of bits so I’m searching for info how to assemble it!

My Mum’s husband won an Airspy HF+ Discovery! Lucky thing.

Now I’m crimping up some cables to try an get a basic working antenna for him. He’s not licensed, so this’ll be SWL. Going to start by lending him a 40m EFHW kit from SOTABEAMS. Totally forgot I had it!

Hearing good things (on the net) about the Antuino ( http://www.hfsignals.com/index.php/antuino/)

First on SolderSmoke and now Hackaday ( https://hackaday.com/2019/09/18/hackable-ham-radio-multitool-contributes-to-long-term-survival-of-the-hobby/)

Time to add one to the Christmas list!

Yay! Sprat! Always an excellent read.

Definitely worth joining the G-QRP club if you aren’t already a member.

The release of CentOS 8 was delayed by the release of 7.7 because the project only has three engineers!

https://lists.centos.org/pipermail/centos-devel/2019-September/017693.html

I wonder how many users there are per engineer. Probably millions!

So, my geiger counter supports serial and wifi, and will report readings to this (insecure) website: http://www.gmcmap.com/ using this (super-dodgy, http only, unauthenticated) API: http://www.gmcmap.com/AutomaticallySubmitData.asp

Presumably this site isn’t intended as anything but a toy!

Everyone is going wild about Chinese NanaVNA clones. They’re tiny, pretty decent, cheap and computer controllable.

There’s a new groups.io group @ https://groups.io/g/nanovna-users and discussions on them almost everywhere.

Mine shipped with no battery, and someone on the users list recommends 602040 Li-Po. I could find something in an old gadget but it would need to be super thin, so I’ve ordered one.

NanoVNA-saver currently looks to be the best software: https://github.com/mihtjel/nanovna-saver

Cool!

Using “the most pointless Docker command ever” ( https://zwischenzugs.com/2015/06/24/the-most-pointless-docker-command-ever/) to look inside the VM Docker for macOS uses.

I’m not sure where the image comes from but it’s pretty small and slick, and I’m unsure how I’d get a shell on it without the hack!

(my next toot will be radio related….maybe)
